How about a copy of the Les Misérables novel by Victor Hugo? You could also consider getting her a DVD of the Les Misérables musical, or tickets to see it live if it's coming to your area. Another option could be a Les Misérables soundtrack featuring her favorite songs from the musical. If she likes to wear jewelry, you could also consider a necklace or bracelet with a quote, lyric or symbol from the musical, such as the iconic barricade or the quote "To love another person is to see the face of God."
Or you can get her a star map with the date of your first kiss.
